Be careful. URIs aren't innovative either. They are just email

Right, a million point to point integrations is basically the same thing
as a unified model.

This is the essence of REST. I feel like you're just arguing for the
kick you get out of it.

"Over the past six years, the REST architectural style has been used to
guide the design
and development of the architecture for the modern Web, as presented in
Chapter 6. This
work was done in conjunction with my authoring of the Internet standards
for the
Hypertext Transfer Protocol (HTTP) and Uniform Resource Identifiers
(URI), the two
specifications that define the generic interface used by all component
interactions on the

"REST therefore gains the separation of concerns of the client-server
style without the server scalability problem, allows information hiding
through a generic interface to enable encapsulation and
evolution of services, and provides for a diverse set of functionality

"REST connectors provide a generic interface for accessing and
manipulating the value set of a resource, regardless of how the
membership function is defined or the type of software that is handling
the request."

"Each origin server provides a generic interface to its services as a
resource hierarchy. The
resource implementation details are hidden behind the interface."

"This constraint sacrifices some of the advantages of other
architectures, such as
the stateful interaction of a relevance feedback protocol like WAIS, in
order to retain the
advantages of a single, generic interface for connector semantics. In
return, the generic
interface makes it possible to access a multitude of services through a
single proxy."
